Type locality. Ritzing ( Austria), Oberpullendorf Basin .
Type stratum. Ritzing Formation.
Age. Late Badenian (Serravallian), Middle Miocene.
Etymology. In honor of Katrin Vohland, director general of the Natural History Museum Vienna ( Austria).
Diagnosis. Medium sized, ovate-naticiform with high, conical spire; weakly concave subsutural ramp; moderately wide, semicircular umbilicus, thickened parietal callus and anterior lobe fused with trigonal umbilical callus.
Description. Medium sized, ovate-naticiform, moderately solid shell of ~4.5 teleoconch whorls; higher than wide (SL/MD = 1.1–1.2). Protoconch poorly preserved, conical, of> two convex whorls. Spire strongly elevated, high conical with moderately convex whorls; apical angle 75–80°. Suture linear, weakly incised. Teleoconch whorls with broad, faintly concave subsutural ramp and convex shoulder. Last whorl weakly expanding, attaining ~80% of total height, weakly concave below adapical suture, strongly convex at periphery and base. Periphery below mid-whorl (~44%). Growth lines delicate, prosocyrt in apical view, subobsolete at periphery. Aperture moderately wide, D-shaped, prosocline. Position of adapical tip of aperture low (~73%), below periphery of penultimate whorl. Aperture attaining ~60% of total height. Columellar lip weakly reinforced, basal lip and outer lip thin. Columellar angle ~17–31°. Opercular ridge in outer lip insignificant. Umbilicus moderately wide (~15%), semicircular, deep with prominent growth lines. Parietal callus long (~54%), strongly thickened, not expanding over base, with straight margin.Anterior lobe of parietal callus thickened, weakly expanding.Funicle weak, fully hidden by trigonal umbilical callus, fused with anterior lobe. Basal fasciole rounded with prominent growth lines. Color pattern not preserved.
Discussion. Euspira vohlandae nov. sp. is characterized by its drop-shaped outline with high, conical spire. Morphologically, it is closest to the early Badenian Euspira vinitor nov. sp., which differs in its more globose last whorl, the much narrower umbilicus and the larger anterior parietal lobe. The spire whorls in E. vinitor are well rounded, whereas in E. vohlandae there is a steep subsutural ramp. Euspira protracta ( Eichwald, 1830) is smaller, has a higher last whorl with more convex subsutural ramp, and has a lower spire. Euspira sirenkoi Pedriali, Sosso & Dell’Angelo, 2019 , has a slenderer, elongate-ovate outline with weakly incised suture and has a much narrower umbilicus.
Paleoecology. Sandy, coastal marine, inner neritic (own data, M.H.).
Distribution in Central Paratethys. Badenian (Middle Miocene): Oberpullendorf Basin: Ritzing ( Austria) ( hoc opus).
